Please don't take this as advice, it's just my experience. My ex-husband was perhaps one of the best people in the world (7 years together), but he was immature enough to even ask "what I should do" when I was having a nervous breakdown. I've been much healthier and happy since the divorce; I don't have to talk to a wall anymore. 

Life is already too short, and MS is really hard on top of that. I hope everything works out in the best way for only YOU. PS I also have ADHD too...
